Jiko and BlackRock Cachematrix Introduce Direct 
T-Bill Ownership

Jiko is bringing access to its 24/7 liquid T-bill offering to BlackRock Cachematrix, one of the world's leading cash management portals, used by institutional investors across 7,000 accounts to manage and allocate operating and reserve cash.

BlackRock Cachematrix users will have the ability to access the Jiko platform and earn the “risk-free” rate in real time with direct U.S. Treasury bill ownership, giving them a way to hold cash that is liquid and earning yield at the same time, with individual ownership easily available from the workflow they already use.

“Treasurers have always had to trade off safety, liquidity, and yield when managing cash, and today's markets are making that trade-off harder to accept,” said Stephane Lintner, CEO of Jiko. “There's no reason operational cash and excess cash should be treated differently. With Jiko, every dollar is safe, liquid, and earning yield at once. Now, Cachematrix clients will access Jiko from the same platform they already use to manage their cash every day.”

Jiko will be one of several offerings within the BlackRock ecosystem, as Cachematrix expands its marketplace in response to client demand for low-risk, short-term investments.

“BlackRock Cachematrix has always been about giving institutional cash managers the best possible toolkit for short-term liquidity,” said Jon Steel, Head of Global Product and Platform, BlackRock Cash Management. “Offering connection to Jiko reflects what we're hearing from clients: they want direct access to additional investment choices, with the transparency and simplicity that direct T-bill ownership provides.”

A New Option for Operating Short-Term Liquidity

Direct T-bill ownership has always required real operational lift: manually selecting maturities, rolling positions, and managing reinvestment cycles. Jiko automates holding cash in T-bills, resolving those traditional frictions. Through BlackRock Cachematrix, users will quickly connect to Jiko and purchase T-bills directly.

Jiko’s proprietary technology auto-selects, auto-rolls, and continuously reinvests, keeping cash fully invested in T-bills at all times at the “risk-free” rate, with instant 24/7 payment and settlement capabilities. No manual sweeps, reinvestment lag, or fund intermediary required.

The demand is real, with 89% of corporate treasurers finding it valuable to hold cash directly in U.S. Treasury bills, while maintaining immediate liquidity for payments. Direct T-bill ownership gives investors full exposure to one of the safest assets available — with complete transparency, constant liquidity, and a yield that reflects the “risk-free” rate.
